Top-roll saddle.

EZRA DIXON, OF BRISTOL, RHODE ISLAND.

TOP-ROLL SADDLE.

To all wh-0m 'it may concern.'

`Be it known that I, EZRA DIXON, a citizen of the United States, residing at Bristol, in the county of Bristol and State of Rhode Island, have invented a new and useful Improvement in Top-Roll Saddles, of which the following is a specification.

This invention pertains to certainnew and useful improvements in Atop roll saddles, used to hold the top rolls in Contact with the drawing rolls of spinning machines, and the primary object of the invention is to provide means for positively limiting movement between the top-and bottom saddles, so that after adjustment of the saddles for spinning ofshort or long ibered staple, accidental movement of the saddles with relation to each other is prevented.

In the drawings-Figure 1 is a fragmentary side elevation, partly in section of a spinning machine, illustrating the present invention applied thereto, the saddle being shown for use in spinning short fibered staple. Fig. 2 is a similar view wherein the saddle is shown for use -in spinning long fibered staple. Fig. 3 is a section on the line 3-3 of Fig. 1, and Fig. 4 is a view similar to Fig. 3, showing the saddles in reversed position, ready for disconnection or adjustment. Y

The invention consists of a bottom saddle 1 which is formed with an upstanding arm 2 that is slotted at 3 the latter leading into an annular aperture 4, t-he aperture being for reception of the shank 5 of the top saddle 6. The shank 5 is preferably circular in cross section so as to be conformably received in the aperture 4, as depicted in Fig. 3 of the drawings. The shank 4 is provided with a series of spaced depending lugs 7, which., when the top saddle is inverted, are capable of passing through the slots 8, as shown in Fig. 4 of the drawings. When the saddles occupy the relative positions shown in Figs. 1 and 2, of the drawings, it will be evident that the lugs v'' which engage on opposite sides of the arm 2 will restrict the sliding movement of the saddles. To change the relative positions of the saddles, they are moved so that the lugs 5 register or aline with the slot 3 of the arm 2, whereupon by sliding movement, the saddles may be adjusted to either of the positions shown in Figs. 1 or 2, or they may be disengaged from one another, as desired.

Serial No. 732,449.

justment of the saddles after they have been once set for the desired staple to be spun.

.It oftentimes happens that a careless op crator in piecing up will move the bottom saddle to the wrong` position, but with the present invention this objection is completely eliminated, and positive assurance `given aga-inst accidental or careless movement of one saddle with relation tothe other.

Having thus described my invention, I claim as new and desire to secure by Letters Patent j 1. In a device of the type described, a top saddle and a bottom saddle adjustable relative to the top saddle. and means to limit said saddles against relative longitudinal movement after adjustment thereof, said /means allowing adjustment or disengagement of the saddles when one of the latter is inverted relative to the other.

2., In a device of the type set forth, a bottom saddle formed with an upstanding arm which is slotted and which has an aperture at the base of the slot, a top saddle formed with a shank receivable through the aperture of said arm land having a series of spaced lugs which are capable of being slid through the slot. said lugs being for engage` ment with opposite sides of the arm.

3. In a device ofthe type set forth, a bottom saddle formed with an upstanding arm which is slotted, and a top saddle formed with a. shank which is slidable through the slot, and means on the shank to prevent disengagement of the saddles, when the latter occupy normal positions.

4. In combination with a top and bottom saddle, means carried by one saddle and being slidably engaged with the other saddle to connect the saddles. and a series of means carried by the last named saddle for cooperation with opposite sides of the firstnamed means to limit relative longitudinal movements ofthe saddles.
